SPECIFICATION forming part of Letters Patent No. 266,735, dated October81, 1882,

Application filed August 2, 1882.

T all whom it may concern 3e it known that I, OHAS.J.VAN DEPOELE, ofChicago, in the county of Cook and State of Illinois, have invented newand useful Improvements in Inductoriums, and I do hereby declare thatthe following is a full, clear, and exact description thereot, referencebeing had to the accom 'ianying drawings, which form a part of thisspecification.

The nature of this invention-relates to certain new and usefulimprovements in the conslruction and operation of a device for thepurpose of producing separate or combined currents of electricity to beused for electric-lighting purposes, the primary current being furnishedby a distant generator, producing alteruate currents inproperly-disposed secondary bobbins not electrically connected with themain current.

The invention consists in the peculiar construction and operation of thedevice, which 1 term an inductorium, as more fully hereinafterdescribed.

Figure 1 is an elevation of my improved inductorium in readiness foruse. Fig. 2 is a vertical section of the same on the line 00 0c in Fig.3. Fig. 3 is a horizontal cross-section on the liney y in Fig. 2. Fig.at is a diagram showing the primary connections. Fig. 5 is a plan viewlooking at the top.

In the accompanying drawings, which form a part of this specification, Gare coarse-wire induction-coils, which will receive the primarycurrentfrom some source of electricity, it being understood that suchcurrent must be continuous, and can be sent from house to house from adistant generator. I are the fine-wire coils, in which the induced orsecondary current is formed or produced, the inner and outer terminalsof said coils being attached to bindingposts 1) n of each individualcoil, whence the current can be led by suitable connections to the workto he done. The secondary coils I are wound upon a soft-iron core, J,and the primary coils G are wound outside the secondary coils,insulating material being placed be tween them. A series of these spoolsof even number--say eightare arranged in a circle upon a suitable baseand secured thereto, and the upper end of each one of the coils isprovided with the binding-posts p n.

F is a tubular socket-standard, screwed or (No model.)

otherwise secured into the base, and supports a spindle, F, uponwhich-is secured a bar-magnet, K; This spindle projects above the magnetK, which latter may be either electro or permanent, although the formeris preferable. Sleeved upon this spindle, above the magnet, is a hub, E,made of some insulatingmaterial, upon which the commutator-plates E aresecured, these plates being of the same number as the bobbins in thegroup, and to each section of the commutator there is connected theprimarycircuit of one of the bobbinsby means of the connecting-wires I),which also support the hub in its position. Secured near the upper endof the spindle, which is hollow atleast for a portion of its upper end,is a bar, a, to each end of which is attached a brush-holder, the onemarked G being in electrical connection with such bar, while the onemarked G is insulated, as shown at G These brush-holders carry thebrushes II I1 in contact with the sections of the commutator.

Vhen the parts described and to be described are all in position and thewhole device ready for operation and suitably connected with the primarycircuit, the magnet K and the brush-holders, which are secured, asdescribed, to the spindle F, rotate with great rapidity, said spindlebeing stepped in the tubular standard for that purpose. The brushholderG is in electrical connection with a connnutator, L, which is securedupon the spindle below the magnet K by a suitable conductor passingthrough the hollow portion of the spindle. A brush-holder, M, is securedto the top of the socket-standard, and carries a brush, M, which hascontact with the ring L. This brush-holder H is insulated from thegeneral frame of the machine, and suitably fastened at the top of thesocket-standard.

N is a wire conductor, connecting with the binding-postN. (Shown inFig.1.) The binding-post I is in electrical contact with the generalframe, while the other one, N, is insulated therefrom. The negativeconductor of a dynamoor other source of electricity is connected to thepost N, and the positive conductor connected to the post I Thecurrententers this latter post, which is in contact with the iron core of onebobbin, which is secured in the metallic base, through which the currentpasses to the socket standard and spindle. The latter,

being in metallic contact with the brushearrier G, allows the current topass through the brush H to the commutator E, which is connected to thecoils G, and as this brush passes only on one side or section ofsaidcommutator the current is conveyed through all the bobbins (in doubleare) at the same time, and on making contact with the insulated brush Hthe circuit will be completed. Now it will be understood that since themagnet K is polarized it will be attracted to the several poles of itsopposite polarity, and begin to rotate with great velocity when thebrushes are put in their proper connection with the commutator. Thus aspeed can be easily obtained ofthree or four thousand revolutions perminute. It will also be understood that since all the primary circuitsare connected together, as shown at Fig. 4that is to say, the inner endof one coil is connected to the outer end of the next through the wholegronp-the current is never broken by the brush traveling over thecommutator, since the current is merely shifted around in direction fromone bobbin to the other, so that no sparks are observed at the brushes.It is this rapid change of polarity in the several bobbins which I makeuse of to induce currents in the secondary coils I. Thus it will be seenthat I can make practical the application of a continuous current toproduce independent alternate currents of higher or lower potential, asmay be required, by proportioning the capacity of the primary andsecondary circuits. The speed can easily be regulated by means of acurrent-regulator or by means of the governor upon which I have alreadysecured Letters Patent.

By the use of the above-described inductorium electricity can bedistributed from house to house by simply locating at each place anapparatus of the proper size. Each one of the bobbins will produce oneor more lights of such size as is needed, the currents being furnishedfrom a station and distributed to consumers.

What I claim as my invention is 1. An inductorium composed of an equalnumber ofindependentinduction-coils, having all the primary circuitsconnected with one another, so that the inner end of one coil iselectrically connected to the outer end of the next through the wholegroup, and in which the outer end of the first coil is connected to theinner end of the last coil in the group, sub stantially as and for thepurpose described.

2. An inductorium having all the primary coils connected together, asdescribed, and to corresponding sections of a stationary COll]l1ll'ltator,provided with cond ucting-brushes whereby on passing theconducting-brushes connected to the source of electricity on oppositesides of said commutator one half of the coils in the group will presentnorth and the other half of said coils south polarity, and on furthermoving said brushes around said commutator the polarity in the group ofcoils will be constantlychangedor shifted as longas the brushes aretraveling, whereby alternating currents are induced in the secondarycoils, substantially as and for the purposes specified.

3. An inductorium having a stationary commutator with insulated sectionscorresponding to the number of inductioneoils in a group,

each section of said commutator being pcrmanently connected to theprimary of one of said induction-coils, the primary circuits beingconnected with each other in a continuous series, in combination withpositive and negative conducting-brushes, leading a currentofelectricitythrough said group of coils, such brushes being adapted to revolvearound said sectional commutator, and thereby to continually change thepolarity of the coils without breaking the circuit, thus avoiding allsparks and allowing the use of continuous primary currents of anydesired strength, si'ibstantially as described.

4. An inductorium having a stationary commutator connected to theprimary coils, connected in a continuous series, as described, andhaving cores inclosed within said coils, in combination with suitablepositive and negative conducting-brushes mounted on a central axis, anda permanent or electro magnet mounted on the same central axis andadapted to be rapidly rotated, together with the said brushes, by theattraction of the cores, caused by their shifting polarity during theprogressive passage therethrough of a continuous main current,substantially as described.

5. The combination of the group of induction-coils secured around andconnected to a stationary central commutator, the centrallyplacedrotating axis carrying conductingbrushes, and a suitableactuating-magnet operated by the shifting polarity of the cores ot' saidinduction-coils, and a ring for conveying the negative current throughthe machine to one of its rotating conducting-brushes, substantially asdescribed.
